' chine for stretching and bending leather for the manufacture of bootsand shoes.

I will now describe my invention with reference to the accompanyingdrawings, in which Figure. 1 shows afront elevation of the ma-' chine.

Fig. 2 shows a sectional elevation on the line A B of Fig. 1; Fig.3 is adetail elevation of one of the rods y,-its socket, and ringnut. Fig. 4is an elevation of part of the lower portion of the machine. Figs. 5 to9, inclusive, are detail sectional views showing the different positionsof the parts in the operation of stretching the leather.

It will be'seen that the machine is supported byfour standards a b c (1,held together by a 1 cross-head g and standing on feet a, the latterbeing connected by the angle-bar f. Be-

.tween the respective standards we and c (1 two racks h slide insuitable grooves (see Fig.

2) and engage with the pinions 'i,.driven by can be disconnected fromthe said racks.

the pinions 1c, fixedon the axle Z, on the end of which is fixed thefly-wheel 'm. The two racks h are connected to the tem let 0 by'thecatch-bolts p, by turning which t e templetlg lower' support g has twoends which slide in the space between the standards. This support isconnected. below and" near the standards to two racks r, which engagewith the pinions s,'-fixed on the axle t, operated by the fly-wheel '11On the same axle tis fixed a toothed wheel 4), with two dogsw. Thesupport (1 is provided with four sockets w, in which are threaded fourscrew-threaded rods y, having each a groove 'y, engaged by a screw ywhich .thus prevents turningof the rods. The rods are raised and loweredby -means of the hand -wheels 2 thereon. The rods at their upper endsare provided with jaws a one fixed to the rod and the other pivoted tothe rod, said jaws being adapted to grip between them the ends of theleather, one of the jaws being adapted to be adjusted toward the otherto eflect the gripping of the v9' are invariably upright;

leather by means of adjusting screws a.

Thus the ends of the leather will be held while being operated upon, aspresently de-' scribed. k The cheeks I) are placed on each side of thetemplet 0 and at a distance which may vary.

rounda pivot e, and the supports (1? have holes'in two places, whichengage with soft friction-pins secured on the checks 1), the obj ectbeing to keep the cheeks and the templet 0 constantly parallel. Theweight of the whole of the support g and of the parts carried by it is'balanced by the counterweight f and'held in sus ension by a belt fpassing overa guide-pu eyf whose shaft is mounted in a standard I), theother end of the belt being secured to a disk or other device f rigidlyconnected with the sup ortg. The jaws but they may be caused to approachor retire symmetrically from the vertical axis of' the machine by meansof the screws h, each provided on its end with right and left handscrew-threads.

These threaded ends engage with threaded by means ofthis rod that thedistance be tween the cheeks is regulated. In order that the jaws 9should stand absolutely vertical, they are kept in position by theangular pieces Z above and by sliding bolts m below, which prevent thesupports (1 from being displaced when the cheeks b are lowered. Thesupports (1 are drawn back when the cheeks b have to be lowered. j

The operation-of the machine is as follows: Let us suppose that thetemplet 0 is fastened to the toothed bars 72. and thatthe templet issufficiently above the cheeks b to allow the necessary space betweenthemfor the leather. First, the pieces of leather 0c are then laid flaton the upper edges of the jaws g. Second, The lower support gbymeans ofthefly-wheel u and its counterweight f is raised until the upper edge ofthe movable cheeks I) touch the lower edges of the jaws g. The opposingedges of the checks 6 and that of the jaws support is brought to astandstill.

g are now close to one another, and the support g is then made immovableby locking the ratchet-wheel v by means of pawls w. Third, the templet 0is then lowered by operating the fly-wheel m, and consequently thepinions 7c Z and the toothed bars h. The templet descending folds theleather double and presses it into the space between the cheeks If thismovement continues, the folds of the leather will be forced against theupper side of the support 9. Fourth, the ratchetwheelv is then released,and when the toothed bars h are further operated the support 9 will beforced to descend under the pressure of the templet 0 until its courseis stopped. The support 9 is sto ped by bolts m, fastened to theuprights a 0 cl, against which'the sides of the support q touch. Whenthe dogs w are brought into contact with the ratchetwheel 4;, thesupport 1 is brought to a standstill. Fifth, if now the back of thepiece of leather is free, this part of the leather is folded over, asseen in Fig. 7, and the edges are seized by the corresponding pincers a.Thereupon the hand-wheels 2 are operated in order to stretch the leatherforcibly until it covers closely the upper part of the templet. Sixth,when the leather has thus been bent and stretched the templet 0 isreleased from its toothed bars or racks r by the catch-bolts p. Then thesupport g is again raised by aid of the fly-wheel it until it is in thesame position as described above in the beginning of the operationthatis to say, that the upper edges of the cheeks b touch against the loweredges of the aws g. Thus in order to effect the contact between theupper side of the cheeks b and the lower side of the jaws g it isnecessary that the templet 0, which rises above the cheeks I), should,together with the leather, enter between the upper jaws g. Seventh, thelower support, the templet 0, and the leather are left in this position.Then the released racks r are again raised sufficiently by the fly-wheelm above the cheeks g in order that a second templet may bebrought intoposition. Then other pieces of leather are placed against the racks rand the second templet is lowered until it comes into contact with thetemplet and its leather left engaged with the lower part of g. Eighth,then the support g is lowered and brought to a standstill by thefly-wheel a. The tongs or pincers a, are loosened. Then after havingwithdrawn the bolts m the space between the cheeks b is diminished fromthe side where the pincers have worked, the said cheeks oscillating onthe pivot e, so that the templet, with the leather enwrapping it, may betaken away. The leather is left on the templet to dry. Ninth, the closedcheek l) is then again opened, the support q is again raised until thecheeks ,I) touch g, and the Then the second templet, which is leftbetween the cheeks g, is lowered and the operation, con tinued asdescribed.

WVhat I claim, and desire to secure by Letters Patent, is-

1. The combination with a supportingframe, of upper cheek-pieces spacedapart as described, lower cheek-pieces also spaced apart, means forraising and lowering the lower cheek-pieces, a templet arranged betweenthe upper and lower cheek-pieces and means for operating the templet.

2. The combination with a supportingframe, of upper cheek-pieces spacedapart as described, lower cheek-pieces also spaced apart, means forraising and lowering the lower cheek-pieces, a templet arranged betweenthe upper and lower cheek-pieces, means for operating the templet, andmeans for adjusting the lower cheek-pieces toward each other to causethem to firmly grip the leather between them and the templet in themanner set forth.

6. In a machine of the character d eseribed, the combination with asupporting-frame, of upper cheek-pieces spaced apart, lower cheekpiecesalso spaced apart, means for raising and lowering the lowercheek-pieces, a templet arranged between the upper and lower.cheek-pieces, means for" operating; the templet, screws h threaded asdescribed and workin in the upper cheek-pieces, the links piecessupported by the standards, lower cheek-pieces, a support g for thelatter cheekpieces, adapted to slide at its ends between the'standards,a counterbalance for the support (1, racks, pinions meshing with theracks, gearing for operating the inions, a templet etachably connectedwit the racks, all arranged as and for the purpose specified.
